Opinions needed. Which tune (M157) - OE or EuroCharged?




Not saying I have an AMS tune
, but if I did, it's pretty awesome! Throttle response, all gears up to 4 are noticeably stronger, and nice bark on the paddle downshifts.. Car is a completely different animal over the stock tune.

Another tuner, "AMR" messaged me on instagram promising some crazy numbers with just a stage 2 tune.. 300 tq..
I find this even more funny because on their website with a dyno tune they don't nearly promise as much as 300 tq...

I have the P30 package so I'm 550/590 stock.
Are you tuned at all?

Eurocharged is equally good and high quality - in the past, they had tuned my C32 and their service was exceptional, Jerry is involved immediately should any glitches arise which they fix and stand by everything they do. of course first and foremost is - best to select a quality tuner local to you should you need to bring the ECU/car back for adjustments. most tuners will ship same day your ECU but having a local option to real time diagnose any glitches and smooth out those in your tune is always good too

Thank you for sharing. I’m in the Bay Area, CA and they’re all too far. Luckily I have another car so I don’t mind shipping the ECU.
I don’t see the tuning industry getting better here in CA with the new automotive laws effective Jan 1, 2019.

, But let's say I do have an AMS ECU-only tune. In this case, the numbers are more like 680-690 Hp, 770 lb-ft, and 11.0- 11.1.To get to 10.5 you will need larger turbos, downpipes, and catless in all likilyhood. You might have to dtch all seats except yours too!
FYI, I am a fan and supporter of the AMS Alpha tune. I am just making sure people are not let down with false expectations.

Does anyone know what the "Alpha Performance bolt-on turbocharger upgrade" entail?
Remember that those packages have been out for about years now and AMS ALPHA have some newer better files. Adding down pipes will only give you say 30hp but with just the ECU tune you can probably still run high 10's on a good run. Keep in mind that the CLS63 is about 200lbs lighter than the E63.

1/4 mile in 10.5sec might be pushing it but it's only 0.3 secs away. Bottomline even if I can get high 10s I will be happy. Heck most GTR's and vettes hit low 11s.
Great points as the tunes were made years ago and I'm sure AMS has made many new advancements. One thing to note for both you and I is that the car in the video is the E63S 2014 model which is 4matic (AWD) which definitely helps with the 1/4 time and it's lighter than our cars. I wonder what our non-4matic CLS's would do with the same tune.
. I haven't done any long highway trips to really check it out, but around town I haven't noticed making more trips to the gas station.
I am still on the fence if I want a tune for my stock 2014 E63 amg S.
looking at these options:
euro charger tune
AMS ECU tune (Currently, top choice)
AMR handheld
Weistec ECU tune
